Referring to the drawings, and tothe em bodiment of the invention whichis selectedfor exemplificat-ion, and having reference at j first moreparticularly to Fig. 1,; tllesrnokebox structure comprises a smoke-box 19jhavg exhaust from which hereinis directed u ward into andthrough the stack, and thee-j" by induces a draft inawell-known manner.

box and thence in an upward and rearward line 88?of margin of'theplate 27 (see Fig. 8) is anar row plate-or strip 34, which ov'erliesithe adjacent'margins of both plates'27 and 27'", and is conveniently secured to the former, as T directionthrough the'spark netting into the pathof the exhaust steam toward the stack,

will now be described, reference being had at first to Fig. 1. v The deflector comprises a rear, generally upright portion designated generally by the numeral; 24, and a lower, generally horizon tal, portion designatedgenerally by the numeral 25. Referring nowto Fig. 2, the rear portionof the deflector comprises upper left and right plates 26 and 26, lowerv leftand right plates 27 and 27 an upper inspection plate 28, and a lower inspection plate 29.; T'IBIBlIlftlljGjPlfitGS 26 and 26 abut against I each other along a line'BO, and to ensure a tight j oint at that point, there is secured to Fig. 5) a narrow strip or plate 31, which overlies the margins of the plates 26 and 26,

joint which prevents sparks from passing through,'- even though the plates shouldbecoine warped 'to quite anextent. Similarly] the plates 27 and 27 abut against each other along aline 33, and secured to an adjacent by rivets 35.

The plates 26 and .27 are secured toflach 1 th b outa pipe, herein a superheater pipe 36, and; the plates 26 and 27". are joined to each other about another pipe, herein a 3 superlieater pipe 36,and to prevent leakage j of' gasesatthese points, there are provided packings 37 and/37V (see Figs. 4 and 6).

Secured to the margins of the plates26 and .95 27are stripsor plates 38and39, as by'rivets =40 and 'These plates are provided with oilset portions 4L2 and 43,.which', together with the adjacent inarginsof the plates 26 i and 27,-present grooves to receive the pack ingf37. Similarly, plates 38 and 39" are, ing a circumferential wall 20, infsecured to the plates 26 and 27, by, rivets its upper portion an opening 21sfo'r, ausual'; stack 22, and in its lower portion an o ening-= 23 for a usual exhaust pipe (not shown), the;

upper edge ofthein'spection plate 29.

The inspection plate 29 may be 'conven iently secured in place by a series of fastenthrough the pin. Like fastening elements are employed for the upper inspection plate. These inspection plates may be provided with appropriate handles 50 and 51 (see be lower portion 25 of the deflector will now be described, reference being bad at first to Fig. 12. In this example, this portion of the deflector comprises asingle plate resenting an opening 52 ,to receive the exbaust pipe. The rear edge of the plate 25' is received in a groove presented" by adjacent marginal-portions; ofthe plates 27 and 27, and flanges presented by angle portions 53 and 53' (see Fig. 2) secure to the plates 27 and 27, respectively.

The; supports for the described, reference being had at first to Fig. 14. The rear deflector, which it will be remembered is composed -of the plates26,

. 126., 27 and 27 has a 'circula-rmarg n, which is-attached to the circumferential" wall; of 5 the smoke-box by appropriate interengag ng.

means,-' herein including a circumferential bar;54.- [I11 ,the present'exampla this bar 18 appropriately securedato the smoke-box wall as rrive fii tongue and c ws connection with the deflector, as by providing. thebar with aninwardly directed 56, which I is received in groove, or rather aisfuccession of grooves, 5?](se lifig. 3), presentedby a series ofbracketsg, whi h are appropriatelyse'cured to the deflector plates,

as by, ri;vetsii59.l Thisinterengagement of a the idefloctor and the smoke-box enables'the vseveral plates,composing thev deflector to be putinplace and securely held without the necessity of employing any iiastenin ,elements, such' as bolts or the like. .It'fo lows thattheremova-lof the deflector plates can i be accomplished with great facility. The

several .plates which compose the rear portion of the deflector are put in place by first introducing: the lower .leftflfand plate 27,

' I then thelower right-handplate 2T then the ,upper left-hand plate 26. then the upper right-lu ndv plate;2i6 and finally the inspection plates .28 and 29, which, by the way,

lock the others inplace.

'Referring again to Fig. 14;,- the front de :flector plate 25 is conveniently supported-at both endsby bars 60,v suitably secured to the circumferential wall-of the, smoke-box as by deflector will now be rivets 61,, said bars presenting inwardly directed flanges 620m which the platcrests. Upward movement of the plate is conveniently prevented by brackets 63 and 64, secured tothe circumferential walls of the smoke-box as by rivets 65 and 66, said brackets being provided with inwardly directed flan es 67 and 68, which, together with the fliinges 62', present a groove or grooves into which the edges of the plate 25 may be introduced by sliding the same in a rearward direction. Herein, the plate 25 has a depending portion 69 (see Fig. 1 to which is secured a damper plate 70, conveniently supported by grooves presented by brackets 71, similar to those just described. 7 i
